肺结核病院内呼吸道感染的临床分析

目的 :研究肺结核病人院内呼吸道感染的临床流行情况及其相关危险因素。方法 :2 0 0 0年 1月至 2 0 0 3年10月实际出院的肺结核病人中符合院内呼吸道感染者逐一填写医院感染病例登记表 ,对表内资料进行回顾性分析。结果 :①肺结核病人院内呼吸道感染发生率 6 .0 %。高危人群为伴有慢性肺部疾患的老年人、肺部以纤维空洞、支气管扩张、肺不张为主要病理损害的肺结核患者。相关危险因素为住院时间长、反复住院、重症结核病所致营养状态低下、大量长期使用广谱抗生素。②铜绿假单孢菌及克雷伯氏杆菌属是本院呼吸道感染的主要致病菌 ,且合并真菌感染率高 ( 4 3.5% )。结论 :结核病人院内呼吸道感染是一个值得重视的问题

Clinical Analysis and Investigation of Respiratory tract Infection on In-patients with Pulmonary Tuberculosis

Objective To study the clinical occurrence and related risk factor inpatients of tuberculosis with respiratory tract infection. Methods Conducting retrospective analysis of pulmonary tu berculosis patients who were discharged from January 2000 to Octerber 2003. Special record forms were filled for every pulmonary TB patients with respiratory tract infection. Results The occurrence rate of respiratory tract infection in patients of pulmonary tuber culosis was 6.0 %.TB patients who were aged, with fibratic cavity, bronehiectasis or atelectasis were more likely to get respiratory tract infection. The high risk factors were long hospitalization duration, frequent hospitalization, malnutrition due to serious TB and long term administration of broad spectrum antibiotics. Pseudomonas aeruginosa and Klebsiclia pneumoniae were the main pathogenic bacteria for infection and 43.5% of the cases were combined with fungus infection. Conclusion Clinical concem should be put to inpatients with pulmonary TB with respiratory tract infection.
